Roof Cleaning · Mount Pleasant, SC
Shingle roofs across Carolina Park and I'On streak dark within a few years, because East Cooper humidity feeds the algae straight through a mild winter. We never put pressure on a roof here - a low-pressure treatment kills the growth down in the granules so the streaks rinse away without costing the shingle any life.
Mount Pleasant, just across the Cooper River from downtown, blends waterfront homes near Shem Creek with fast-growing subdivisions out toward Park West and Carolina Park. Salt air off the creeks and harbor plus Lowcountry humidity leave driveways, siding, and roofs coated in algae and mildew. A soft-wash lifts that buildup without harming siding or fresh finishes.
Homes from Shem Creek out to Park West fall under the same East Cooper public services published by Charleston County.
The tide and storm news that decides when marsh salt film settles heaviest here is tracked daily in The Post and Courier.

Those dark streaks running down Charleston roofs are not dirt; they are Gloeocapsa magma, a hardy algae that thrives in the Lowcountry's heat and humidity and slowly feeds on the limestone filler in asphalt shingles. Under a heavy canopy of live oaks dripping with Spanish moss, growth comes back fast, and pressure would tear granules right off the shingle. We never pressure-wash a roof. Instead we soft wash at less than garden-hose pressure, applying a treatment that kills algae, lichen and moss at the root so the roof rinses clean and stays clean far longer. The same careful chemistry works on the metal and slate roofs common downtown and in the Old Village, where a single misstep is costly. From Sullivan's Island to Summerville, we protect the roof's life while clearing the stains that age a house before its time.
